Warning:

Today may introduce BIC changes to KConfigSkeleton (changes in the virtual
table layout). Make sure to clean up your build dir[1] after today.

[1] Hint for cleaning up the build dir, if you're using zsh with
extendedglob:
  $ cd kdelibs-build
  $ rm -rf *~CMakeCache.txt
  $ cmake /path/to/kdelibs-src
  $ make
